In addition, provided are a film, a laminate, an infrared transmitting filter, a solid image pickup element, and an infrared sensor. This composition includes: a coloring material that allows transmission of infrared light and shields visible light; an infrared absorber; and a curable compound, in which the infrared absorber includes a material that shields light in a wavelength range of longer than 1000 nm and 1200 nm or shorter. In the composition, a ratio A/B of a minimum value A of an absorbance of the composition in a wavelength range of 400 to 1100 nm to a maximum value B of an absorbance of the composition in a wavelength range of 1400 to 1500 nm is 4.5 or higher.
